Light source comprising a substrate and a heat sink structure
The present invention relates to a light source (100) comprising a substrate (110) having a slit (112) and a sheet formed heat sink structure (120) comprising a plurality of LEDs (130), wherein the plurality of LEDs are arranged at a surface (122) of the heat sink structure and wherein the heat sink structure is mounted through the slit such that a LED comprising portion (124) of the heat sink structure, extending from a first side (114) of the 5 substrate, and a heat-emitting portion (126) of the heat sink structure, extending from a second side (116) of the substrate being opposite to the first side, are formed. A lighting system comprising such a light source is also presented.
Luminaire for generating direct lighting and indirect lighting
A luminaire comprises a first light exit opening for emitting light from at least two light sources. A diffusely-reflecting first reflector portion is arranged on an inner side of a luminaire body. A first light source is arranged in an edge portion of the luminaire body surrounding the first light exit opening. First light beams of the first light source are deflected towards the first reflector portion by a second reflector portion, so that said beams exit through the first light exit opening as a diffusely-reflected first light beam bundle. A second light source generates a second light beam bundle. The first light beams exit the luminaire body exclusively as first light beams reflected at the first reflector portion. A second light exit opening is surrounded by the first reflector portion. A second aperture angle of the second light beam bundle is smaller than the first aperture angle.
Temporary light strip system
A modular system of light strips is configured for use on a roadway surface. The light strips are configured to withstand vehicular traffic driving over the light strips. The light strips have a rigid, durable housing protecting a series of LEDs within the housing. LED lenses direct light from the LEDs through the sidewall of the housing at vehicular traffic on the roadway. The channel is filled with a protective material, such as a polymer resin that protects the LEDs and power supply. The modular system includes a power source or can connect to a power grid. The modular system can include a sensor to activate the system and/or to control the light brightness Preferably the light strips connect together or can be substituted for one another to be interchangeable and easily carried, moved, installed and disassembled.
Method for manufacturing a lighting device
A method is provided, wherein a lighting device (200, 300, 400, 500) comprising an at least partly light transmitting envelope (110) and a solid state light source (120) is manufactured. The method comprises arranging (710) an at least partly light transmitting plastic material (140) in a mold (130) having a surface structure (132) arranged on an inner surface portion of the mold and blow molding (720) the plastic material so as to form the envelope. During the blow molding, the surface structure is at least partly transferred to the at least partly light transmitting plastic material, thereby forming an optical structure (150) on a portion of an outer surface of the envelope. The envelope is then removed (730) from the mold and arranged (740) to at least partly enclose the solid state light source. The optical structure may be formed to generate a desired optical effect.
Convertible light device
The disclosure includes a convertible light device comprising a device housing, a battery pack removably coupled to the housing, and an elongate flexible light source detachably coupled to the device housing and electrically coupled to the battery pack, where the elongate flexible light source comprises a plurality of LEDs. In some embodiments, the convertible light device is configured to convert between a rope mode and a lantern mode. In the rope mode, the elongate flexible light, source may be configured to extend from the device housing. In the lantern mode, the elongate flexible light source may be configured to wrap around the device housing.
Paper dispenser and method of using same
A paper dispenser for dispensing paper provided on a roll may include a cylindrical housing having a compartment dimensioned to receive the roll and a slot provided between an inner and an outer surface of the cylindrical housing to dispense paper from the roll. End walls may be removably provided proximate to longitudinal ends of the cylindrical housing. The paper dispenser may also include a decorative layer and a layer of absorptive material for dispensing fragrance. Additionally or alternatively, the dispenser may employ a flexible rod that supports the paper roll in a position that is further away from a support structure than would be possible with a rigid rod, and may provide illumination functionality.
Tape light termination system
A tape light termination system includes a terminal in a housing. The terminal includes an electrically conducting contact area and a termination lug to fixedly connect an electric conductor with the terminal and provide an electrically conducting path between the termination lug and the contact point. The housing includes compartments sized to receive and hold the terminal, and slots which are positioned and dimensioned to receive opposing edges of a light emitting diode (LED) tape light. The LED tape light includes a flexible strip having LED diode circuitry and an electrically conductive pad on the planar surface. Each of the slots provide access in the housing to the electrically conductive contact area and alignment of the electrically conducting contact area of the terminal to contiguously contact the electrically conductive pad and enable a current flow path therebetween.
LED light tubes, light boxes including LED light tubes and methods for installation of LED light tubes in light boxes
Light emitting diode (LED) light tubes having rotatable end cap assemblies are described. The LED light tubes include a hollow tube and a circuit board with LED chips thereon. The end cap assemblies are provided on either end of the tube. Each end cap assembly includes a socket cap, a plug having a plug body and at least one connector, and an end cap body, one end of which engages one of the ends of the hollow tube. A cam locking mount that is positioned within the plug body and on the opposite side has projections to be positioned in the bore of the end cap body. A rotation cam is seated in the cam locking mount and provides for controlled rotation of the LED tube relative to the end caps. Methods of installing the LED light tubes in new installations and retrofit installations and for use in sign assemblies are also described.
